Chocolate Scones

from Bite Me (cookbook)

3 1/4 cups flour
1/2 cup sugar
2 tsp baking powder
1 tsp baking soda
1/2 tsp kosher salt
1/4 tsp ground cinnamon
3/4 cup cold butter, cut into small pieces
1 1/2 cups semi-sweet chocolate chips
1 cup buttermilk
1/4 tsp vanilla

Sugar topping:
2 Tbsp melted butter
2 Tbsp sugar

Directions:
1.  Preheat oven to 425 degrees.  Line a baking sheet with parchment paper.
2.  In a large bowl, sift together flour, sugar, baking powder, baking soda, salt, and cinnamon.  Cut in butter using a pastry blender until mixture resembles coarse meal.  Stir in chocolate chips.  Add buttermilk and vanilla, stirring just until moistened.
3.  Turn dough onto a lightly floured surface and knead briefly, 5 or 6 times, to gather into a ball (do not keep kneading!).  Divide the ball in half and gently pat each into an 8-inch flat round.  Brush the top of each with melted butter and sprinkle with sugar.
4.  Using a sharp knife, but each circle into 6 even triangles and place on baking sheet, about 1 inch apart.  Bake 16-18 minutes or until tops are golden.
